Paul vs. Peter: The Most Important Confrontation in the Early Church
Galatians 2:11–21
In Galatians 2:11–21, the Apostle Paul recounts one of the most significant moments in early church history: his public confrontation with the Apostle Peter in Antioch. This was not a personal dispute, but a theological crisis that struck at the very heart of the gospel itself.
Peter had been freely eating and fellowshipping with Gentile believers. However, when certain men from Jerusalem arrived, Peter withdrew out of fear and separated himself. His actions implied that Gentile believers were somehow spiritually inferior unless they adopted Jewish customs and practices. Paul recognized immediately that this behavior contradicted the truth of the gospel and publicly rebuked Peter for it.
At the core of Paul’s argument is the doctrine of justification by faith alone. Both Jews and Gentiles, Paul explains, are sinners and stand equally in need of salvation. No one is declared righteous by works of the law—whether Mosaic law or any system of human effort—but only through faith in Jesus Christ.
Paul then moves beyond the confrontation and gives one of the most profound theological statements in all of Scripture:
“I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me.” (Galatians 2:20, NASB 1995)
Here, Paul describes what it means to be “in Christ”—a complete union with Christ in which the believer’s old identity is replaced by a new life grounded entirely in faith. Salvation is not achieved by human obedience, moral effort, or religious performance, but by participation in the life, death, and resurrection of Christ.
Paul concludes with a powerful and emotional declaration:
“I do not nullify the grace of God, for if righteousness comes through law, then Christ died needlessly.” (Galatians 2:21)
If righteousness could be gained by anything we do, then the cross was unnecessary. But because salvation is entirely an act of divine grace, Christ alone is the foundation of our hope.
This passage stands as one of the clearest and strongest affirmations in the New Testament that salvation is by grace alone, through faith alone, in Christ alone.
